   Object Recognition Image Database

The image sets listed below accompany the publication  "Is colour constancy good enough?" [ECCV '98] .

 Camera and Capture Settings

All images were captured with a Sony DXC-930 3 CDD digital video camera using the following settings:

  • Gamma Correction  : OFF
  • Colour Tempurature: 3200 K
Each object in the database was placed in a Macbeth Judge II light booth, and an image was captured of the object under five different illuminants. The camera aperture was adjusted to prevent image clipping under the brightest lighting conditions for a given object, and not changed between illuminants.

 Image Database Contents


The following objects form the database:
Object Name Description
ball1 Fuzzy fluorescent ball.
ball2 Shiny multicoloured ball.

Image Sets

The image database consists of two sets, the Model and Test databases:
  • Model Database - images of objects in a fixed orientation, captured under 5 different illuminants.
  • Test Database - images of objects in a random orientation, captured under the same 5 illuminants as the model database.
Example of model and test images for "ball2".
